This campaign will deploy 44 custom high-altitude in-situ instruments called HYFLITS (\u0027Hypersonic Flight in the Turbulent Stratosphere\u0027) to characterize turbulence in the troposphere and lower stratosphere, as well as conduct intercomparisons with the VHF PANSY radar (\u2018Program of the ANtarctic SYowa\u2019) observations and concurrently deployed LODEWAVE (LOng-Duration balloon Experiment of gravity WAVE over Antarctica) observations.\r\nThis research is motivated by the fact that the sources representing realistic multi-scale gravity wave (GW) drag, and Kelvin Helmholtz Instability (KHI) dynamics in enhanced shear flows, and their contributions to momentum/energy budgets due to turbulent transport/mixing, are largely missing in the current state-of-the-art General Circulation Model (GCM) parameterization schemes. This results in poor and unreliable model forecasts of flow features from local to synoptic scales at southern high latitudes. \r\nThe proposed research aims to utilize high-resolution in-situ turbulence instruments to characterize the multi-scale GW sources and breaking, KHI instabilities emerging in a wide range of scales, Reynolds and Richardson numbers, and background GW environments in the coastal Antarctic region and quantify their contributions to the momentum and turbulence energy budgets in the tropo-stratosphere. Specific research objectives include the following:\r\n1.\tCharacterize the large-scale dynamics of orographic GWs produced by katabatic forcing and non-orographic GWs produced by summer tropopause jets and low-pressure synoptic-scale events employing targeted HYFLITS and LODEWAVE measurements in conjunction with PANSY radar observations.\r\n2.\tQuantify the GW momentum fluxes using HYFLITS and LODEWAVE measurements, and the turbulence dissipation rates using HYFLITS and PANSY radar measurements for representative multi-scale GW and KHI events to assess the zonal and meridional energy and constituent transport, and the variability in turbulence intensities/mixing throughout the troposphere and lower stratosphere.\r\nThe project will deploy the low-cost HYFLITS systems equipped with custom in-situ turbulence and radiosonde instruments at Syowa station.
